Definitions
- This invention relates to a seat slide apparatus for a vehicle of which an upper rail is fixed with a seatbelt anchor.
- the seat slide apparatus disclosed in the reference 1 includes a lower rail and an upper rail.
- the lower rail is fixed to a vehicle floor while the upper rail is secured to a seat of the vehicle and is movably supported relative to the lower rail.
- the upper rail is fixedly provided with a belt anchor bracket (upper bracket) to which a belt anchor is fixed.
- An engaging plate is fixedly attached to a lower surface of the lower rail, and an end of the engaging plate is formed with an engaging rail.
- the belt anchor bracket (upper bracket) is fixed with a belt anchor plate.
- a lower end portion of the belt anchor plate is fixed to a sidewall portion of the upper rail by welding or the like.
- the lower end portion of the belt anchor plate is formed with a belt anchor piece which faces the engaging rail of the engaging plate.
- the lifting load when a lifting load is applied to the belt anchor, the lifting load is dispersedly transmitted over the upper rail 12 via the belt anchor bracket (upper bracket) and the belt anchor plate. Additionally, the lifting load is transmitted to the lower rail because the engaging piece is engaged with the engaging rail. Therefore, according to the seat slide apparatus in the reference 1, the lifting load received by the belt anchor is also received on the whole of the lower rail and the upper rail. Accordingly, detachment durability, for resisting a detachment of the upper rail from the lower rail, is increased.
- the seat slide apparatus of the reference 2 includes a lower rail and an upper rail.
- the lower rail is fixed to a vehicle floor, and the upper rails is secured to a seat of the vehicle and movably supported relative to the lower rail.
- the upper rail is fixedly provided with a belt anchor bracket to which a belt anchor (seatbelt anchor) is fixed.
- An approximately inverted J-shaped hook member is fixedly attached inside the upper rail to be adjacent to the belt anchor bracket.
- a screw spindle is unrotatably secured to the lower rail. The screw spindle is provided for changing a motor rotation to a longitudinal movement of the upper rail.
- the lifting load is transmitted to the upper rail. Then, the lifting load is further transmitted to the lower rail because the hook member is engaged with the screw spindle. Therefore, according to the seat slide apparatus disclosed in the reference 2, the lifting load received by the belt anchor (seatbelt anchor) is received on whole of the lower and upper rails. Accordingly, detachment durability, for resisting a detachment of the upper rail from the lower rail, is increased.
- the seat slide apparatus for the vehicle according to the reference 1 requires not only the belt anchor bracket (upper bracket) but also the engaging plate and the belt anchor plate. Further, the seat slide apparatus for the vehicle according to the reference 2 requires not only the belt anchor bracket but also the hook member. Therefore, according to each seat slide apparatus for the vehicle disclosed in the reference 1 and in the reference 2, an amount of components and the number of jointing positions are increased. Accordingly, a manufacturing cost may be increased and further, there is a possibility that a sliding resistance and a noise may be generated.

Therefore, according to the seat slide apparatus for the vehicle described above, the lifting load is received on both lower and upper rails. Further, the seat slide apparatus for the vehicle according to the present invention may not require further components than the belt anchor bracket in order to enhance detachment durability. Therefore, both an amount of components and the number of jointing positions can be reduced. Consequently, a manufacturing cost can be reduced, and a sliding resistance and a noise are prevented from being generated.

- the rail fixing portion includes an extending portion extending in a forward direction of the upper rail.
- the belt anchor bracket extends in a forward direction of the upper rail. Accordingly, when the lifting load is applied to the belt anchor bracket, the lifting load is transmitted to the upper rail via the rail fixing portion, and further transmitted to the lower rail because the load distribution portion makes contact with and presses the lower rail. Therefore, the releasing load is received on both the lower and upper rails.
- the seat slide apparatus for the vehicle according to the present invention may not require further components than the belt anchor bracket in order to enhance detachment durability. Therefore, both an amount of components and the number of jointing positions can be reduced. Consequently, a manufacturing cost can be reduced, and a sliding resistance and a noise are prevented from being generated.

- the load distribution portion includes a sidewall portion downwardly extending from the rail fixing portion and a bottom portion extending from a lower portion of the sidewall portion in a lateral direction of the seat.
- the bottom portion which extends from the lower edge portion of the sidewall portion, presses the lower rail. Accordingly, a contacting area of the load distribution portion with the lower rail may be larger and the rigidity of the belt anchor bracket may be increased.
- a reinforcement member is provided at the rail fixing portion of the belt anchor bracket, and the reinforcement member enhances rigidity of the belt anchor bracket.
- a lock mechanism for releaseably locking the upper rail relative to the lower rail.
- the lock mechanism includes a lock portion provided at the lower rail, a lock member pivotably supported by the upper rail and being engageable with and disengageable from the lock portion, and the lock bracket serving as a reinforcement member for supporting the lock member.
- the reinforcement member enhances the rigidity of the belt anchor bracket. Accordingly, the detachment durability is enhanced.

- a component force F1 of the lifting load F is produced in a vertical direction relative to the lower rail 10 and the upper rail 20. Accordingly, a left rotation moment (F1 ⁇ L1) is generated relative to a center O of the belt anchor bracket 50. Therefore, the belt anchor bracket 50 starts rotating left around the center O and accordingly, the upper rail 20 starts flexing or bending to be lifted up from the lower rail 10 in a direction from a rear portion towards a front portion, of the upper rail 20.
- the bottom portion 54b of the load distribution portion 54 when the bottom portion 54b of the load distribution portion 54 makes a contact with and presses the upper portion 14b, the bottom portion 54b receives a counter force F2 from the lower rail 10 in a vertical direction relative to the lower rail 10.
- the counter force F2 is produced by the load distribution portion 54 pressing the upper portion 14b of the lower rail 10, and therefore, a right rotation moment (F2 ⁇ L2) is generated relative to the center O of the belt anchor bracket 50.
- the left rotation moment (F1 ⁇ L1) generated by the component force F1 is lowered by the right rotation moment (F2 ⁇ L2) generated by the counter force F2.
- the upper rail 20 is restrained from being separated or lifted up from the lower rail 10.
- the belt anchor bracket 50 extends in a front direction of the upper rail 20. Accordingly, when the lifting load F is applied to the belt anchor 60, the lifting load F is dispersed to the front direction of the upper rail 20 and transmitted over the upper rail 20, via the rail fixing portion 51 of the belt anchor bracket 50. Furthermore, the lifting load F is transmitted to the lower rail 10 because the load distribution portion 54 of the belt anchor bracket 50 makes a contact with and presses the lower rail 10. Therefore, according to the seat slide apparatus of the present invention, the lifting load F is received not only by the belt anchor 60 but also by the lower rail 10 and the upper rail 20.
- the seat slide apparatus for a vehicle may not require further components than the belt anchor bracket 50 in order to enhance detachment durability, which is a degree of resistance of the upper rail 20 to be retained at an original position relative to the lower rail 10. Therefore, both an amount of components and the number of jointing positions can be reduced. Consequently, according to the seat slide apparatus of the present embodiment, the detachment durability can be enhanced and a manufacturing cost can be reduced. Further, a sliding resistance and a noise are prevented from being generated.
- the lock bracket 32 serving as the reinforcement member is provided at the rail fixing portion 51 of the belt anchor bracket 50 in order to enhance the rigidity of the belt anchor bracket 50. Accordingly, the detachment durability may be further enhanced, and an amount of the components and the number of the jointing positions may be reduced.
- the bottom portion 54b extending from the lower edge portion of the sidewall portion 54a outwardly in a lateral direction of the seat 91, presses the lower rail 10. Accordingly, a contacting area of the load distribution portion 54 with the lower rail 10 may be larger and the rigidity of the belt anchor bracket 50 may be increased.
- the load distribution portion 54 makes a contact with the lower rail 10 in a condition where a load, which is larger than a predetermined value, is applied to the belt anchor bracket 50. Therefore, the upper rail 20 is normally not prevented from smoothly sliding relative to the lower rail 10.
- a seat slide apparatus for a vehicle includes a lower rail (10), an upper rail (20), a lock mechanism (30) releaseably locking the upper rail (20) relative to the lower rail (10), and a belt anchor bracket (50) fixedly provided to the upper rail (20) and attached with a belt anchor (60).
- the belt anchor bracket (50) includes a rail fixing portion (51) having a plane surface being parallel to the upper surface of the upper rail (20) and attached to the upper surface of the upper rail (20), a load distribution portion (54) downwardly extending from the rail fixing portion (51) and being adjacent to an upper surface of the lower rail (10), and an anchor fixing portion (52) upwardly extending from the rail fixing portion (51) for anchoring the belt anchor (60).
Abstract
Description
- This invention relates to a seat slide apparatus for a vehicle of which an upper rail is fixed with a seatbelt anchor.
- A known seat slide apparatus for a vehicle is disclosed in a
Japanese Examined Utility Model Application Publication No. 08-10038 - According to the seat slide apparatus in the reference 1, when a lifting load is applied to the belt anchor, the lifting load is dispersedly transmitted over the upper rail 12 via the belt anchor bracket (upper bracket) and the belt anchor plate. Additionally, the lifting load is transmitted to the lower rail because the engaging piece is engaged with the engaging rail. Therefore, according to the seat slide apparatus in the reference 1, the lifting load received by the belt anchor is also received on the whole of the lower rail and the upper rail. Accordingly, detachment durability, for resisting a detachment of the upper rail from the lower rail, is increased.
- Further, a known seat slide apparatus for a vehicle is disclosed in
Japanese Patent No. 2004-106713A - According to the seat slide apparatus disclosed in the reference 2, when a lifting load is applied to the belt anchor (seatbelt anchor), the lifting load is transmitted to the upper rail. Then, the lifting load is further transmitted to the lower rail because the hook member is engaged with the screw spindle. Therefore, according to the seat slide apparatus disclosed in the reference 2, the lifting load received by the belt anchor (seatbelt anchor) is received on whole of the lower and upper rails. Accordingly, detachment durability, for resisting a detachment of the upper rail from the lower rail, is increased.
- However, the seat slide apparatus for the vehicle according to the reference 1 requires not only the belt anchor bracket (upper bracket) but also the engaging plate and the belt anchor plate. Further, the seat slide apparatus for the vehicle according to the reference 2 requires not only the belt anchor bracket but also the hook member. Therefore, according to each seat slide apparatus for the vehicle disclosed in the reference 1 and in the reference 2, an amount of components and the number of jointing positions are increased. Accordingly, a manufacturing cost may be increased and further, there is a possibility that a sliding resistance and a noise may be generated.
- A need thus exists for a seat slide apparatus for a vehicle which achieves increasing detachment durability and reducing the manufacturing cost, and which reduces a generation of the sliding resistance and the noise.
- According to an aspect of the present invention, a seat slide apparatus for a vehicle includes a lower rail which is fixedly mounted on a vehicle floor, an upper rail which is coupled to a seat of the vehicle and movably supported by the lower rail, and a lock mechanism which releaseably locks the upper rail relative to the lower rail. The seat slide apparatus for the vehicle according to an aspect of the present invention further includes a belt anchor bracket which is fixedly provided at the upper rail and attached with a belt anchor. The belt anchor bracket includes a rail fixing portion having a plane surface being parallel to the upper surface of the upper rail and attached to the upper surface of the upper rail, a load distribution portion downwardly extending from the rail fixing portion and being adjacent to an upper surface of the lower rail, and an anchor fixing portion upwardly extending from the rail fixing portion for anchoring the belt anchor.
- Due to the above described structure, the seat slide apparatus for the vehicle includes the load distribution portion. Accordingly, when a lifting load is applied to the belt anchor bracket, the lifting load is transmitted to the upper rail from the belt anchor bracket, and further transmitted to the lower rail because the load distribution portion of the belt anchor bracket makes a contact with and presses the lower rail. Therefore, according to the seat slide apparatus for the vehicle described above, the lifting load is received on both lower and upper rails. Further, the seat slide apparatus for the vehicle according to the present invention may not require further components than the belt anchor bracket in order to enhance detachment durability. Therefore, both an amount of components and the number of jointing positions can be reduced. Consequently, a manufacturing cost can be reduced, and a sliding resistance and a noise are prevented from being generated.
- Further according to an aspect of the present invention, it is preferable that the belt anchor bracket includes a rail fixing portion having a plane surface being parallel to an upper surface of the upper rail and attached to the upper surface of the upper rail, the load distribution portion downwardly extending from the rail fixing portion and being adjacent to an upper surface of the lower rail, and an anchor fixing portion upwardly extending from the rail fixing portion for anchoring the belt anchor.
- It is further preferable that the rail fixing portion includes an extending portion extending in a forward direction of the upper rail.
- Due to the above described structure, the belt anchor bracket extends in a forward direction of the upper rail. Accordingly, when the lifting load is applied to the belt anchor bracket, the lifting load is transmitted to the upper rail via the rail fixing portion, and further transmitted to the lower rail because the load distribution portion makes contact with and presses the lower rail. Therefore, the releasing load is received on both the lower and upper rails. Further, the seat slide apparatus for the vehicle according to the present invention may not require further components than the belt anchor bracket in order to enhance detachment durability. Therefore, both an amount of components and the number of jointing positions can be reduced. Consequently, a manufacturing cost can be reduced, and a sliding resistance and a noise are prevented from being generated.
- It is still further preferable that the belt anchor bracket makes a contact with the lower rail when a load being equal to or exceeding a predetermined value is applied to the belt anchor bracket.
- Due to the above described structure, the load distribution portion makes a contact with the lower rail in a condition where a load, which is equal to or larger than a predetermined value, is applied to the belt anchor bracket.

Theload distribution portion 54 includes asidewall portion 54a and abottom portion 54b. Thesidewall portion 54a downwardly extends from the outer edge of the extendingportion 51a, and thebottom portion 54b extends from a lower end of thesidewall portion 54a outwardly in a lateral direction of theseat 91. Thebottom portion 54b can be arranged in parallel with theupper wall 14b of thelower rail 10. Further, thebottom portion 54b is arranged adjacently to theupper wall 14b of thelower rail 10. In other wards, thebottom portion 54b is arranged to be adjacent to theupper rail 14b at a portion vertically lower than a position where therail fixing portion 51 is arranged. Further, theanchor fixing portion 52 upwardly extends from an outer edge of thebottom wall 54b. More specifically, as illustrated in Fig. 6, theload distribution portion 54 is formed at a center O of thebelt anchor bracket 50 and extends from the center O of thebelt anchor bracket 50 in a front direction of thebelt anchor bracket 50 with the longitudinal length L2. Here, the center O is assigned as a position, which is distant with the longitudinal length L1 in a forward direction of the vehicle from a position located at therail fixing portion 51 in a vertically downward direction from a central position (serving as a belt anchor fixing position) of theanchor fixing bolt 52a. In other wards, theload distribution portion 54 is formed with the length L2 in the longitudinal direction of the seat slide apparatus for the vehicle. In addition, it is preferable that an equation "L1 < L2" (the length L2 is longer than the length L1) is applied to a relation of the lengths L1 and L2. However, the equation is not necessarily limited to the above. Alternatively, equations "L1 =L2" and "L1 > L2" are also applicable. As described above, thebelt anchor bracket 50 additionally includes a portion extending in a front direction of theupper rail 20. Further, thelock bracket 32 is provided between the extendingportion 51a of thebelt anchor bracket 50 and theupper wall 21 of theupper rail 20. Thelock bracket 32 serves as a reinforcement member, which enhances rigidity of thebelt anchor bracket 50. In the mean time, the rigidity of thebelt anchor bracket 50 is increased by the extendingportion 51a, which extends from the front portion of therail fixing portion 51. Accordingly, the extendingportion 51a may also serve as a reinforcement member for enhancing the rigidity of thebelt anchor bracket 50. - The
belt anchor 60 includes abuckle 61, abuckle retaining member 62 and a fixingmember 63. Theanchor fixing bolt 52a of theanchor fixing portion 52 is inserted into the fixingmember 63 and is connected thereto with anut 64, and therefore, thebelt anchor 60 is fixedly attached to thebelt anchor bracket 50. - According to the above mentioned seat slide apparatus, as illustrated in Fig. 6, when an excessively large lifting load F is applied to the
belt anchor 60, a component force F1 of the lifting load F is produced in a vertical direction relative to thelower rail 10 and theupper rail 20. Accordingly, a left rotation moment (F1 × L1) is generated relative to a center O of thebelt anchor bracket 50. Therefore, thebelt anchor bracket 50 starts rotating left around the center O and accordingly, theupper rail 20 starts flexing or bending to be lifted up from thelower rail 10 in a direction from a rear portion towards a front portion, of theupper rail 20. However, when thebottom portion 54b of theload distribution portion 54 makes a contact with and presses theupper portion 14b, thebottom portion 54b receives a counter force F2 from thelower rail 10 in a vertical direction relative to thelower rail 10. As described above, the counter force F2 is produced by theload distribution portion 54 pressing theupper portion 14b of thelower rail 10, and therefore, a right rotation moment (F2 × L2) is generated relative to the center O of thebelt anchor bracket 50. Accordingly, the left rotation moment (F1 × L1) generated by the component force F1 is lowered by the right rotation moment (F2 × L2) generated by the counter force F2. Then, theupper rail 20 is restrained from being separated or lifted up from thelower rail 10. - According to the present embodiment of the seat slide apparatus for the vehicle, the
belt anchor bracket 50 extends in a front direction of theupper rail 20. Accordingly, when the lifting load F is applied to thebelt anchor 60, the lifting load F is dispersed to the front direction of theupper rail 20 and transmitted over theupper rail 20, via therail fixing portion 51 of thebelt anchor bracket 50. Furthermore, the lifting load F is transmitted to thelower rail 10 because theload distribution portion 54 of thebelt anchor bracket 50 makes a contact with and presses thelower rail 10. Therefore, according to the seat slide apparatus of the present invention, the lifting load F is received not only by thebelt anchor 60 but also by thelower rail 10 and theupper rail 20. Further, the seat slide apparatus for a vehicle according to the present invention may not require further components than thebelt anchor bracket 50 in order to enhance detachment durability, which is a degree of resistance of theupper rail 20 to be retained at an original position relative to thelower rail 10. Therefore, both an amount of components and the number of jointing positions can be reduced. Consequently, according to the seat slide apparatus of the present embodiment, the detachment durability can be enhanced and a manufacturing cost can be reduced. Further, a sliding resistance and a noise are prevented from being generated. - Further according to the seat slide apparatus of the present invention, the
lock bracket 32 serving as the reinforcement member is provided at therail fixing portion 51 of thebelt anchor bracket 50 in order to enhance the rigidity of thebelt anchor bracket 50. Accordingly, the detachment durability may be further enhanced, and an amount of the components and the number of the jointing positions may be reduced. - Further according to the seat slide apparatus of the present invention, the
bottom portion 54b, extending from the lower edge portion of thesidewall portion 54a outwardly in a lateral direction of theseat 91, presses thelower rail 10. Accordingly, a contacting area of theload distribution portion 54 with thelower rail 10 may be larger and the rigidity of thebelt anchor bracket 50 may be increased. - Still further according to the seat slide apparatus of the present invention, the
load distribution portion 54 makes a contact with thelower rail 10 in a condition where a load, which is larger than a predetermined value, is applied to thebelt anchor bracket 50. Therefore, theupper rail 20 is normally not prevented from smoothly sliding relative to thelower rail 10. - The principles, preferred embodiment and mode of operation of the present invention have been described in the foregoing specification. However, the invention, which is intended to be protected, is not to be construed as limited to the embodiment disclosed. Further, the embodiments described herein are to be regarded as illustrative rather than restrictive. Others may make variations and changes, and equivalents employed, without departing from the spirit of the present invention. Accordingly, it is expressly intended that all such variations, changes and equivalents that fall within the spirit and scope of the present invention as defined in the claims, be embraced thereby.
